BIRD-GUARD.

Specification of Letters Patent. Patentetl Sept. 5, 1916- Application filed February 10, 1915. Serial No. 7,427.

To all whom it may concern:

Be it known that I, ARTHUR AnoTIL, a citizen of the United States, residing at Taunton, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Bird-Guards, of which the following is a specificat on, reference being had to the accompanying drawings.

This invention relates to bird guards, and has for its primary object to provide a very simple and effective device of this character which will prevent sparrows, plgeons, and other birds from roosting upon blmds or fastening means therefor projecting from the wall of the building.

The invention has for a more particular object to provide a device of this character embodying a pin or spur provided with a novel form of clamp on one end, whereby the spur may be easily and quickly attached to the hold-back iron for a blind or readily removed therefrom.

With the above and other objects in view, my invention consists in the novel features of construction, combination, and arrangement of parts to be hereinafter more fully described, claimed, and illustrated in the accompanying drawing, in which,

Figure 1 is a side elevation illustrating my improved bird guard applied to the holdback iron for a window blind; Fig. 2 is a section taken on the line 22 of Fig. 1; Fig. 3 is an end elevation of the guard device.

Referring in detail to the drawing and more particularly to Figs. 1, 2 and 3 thereof, 5 designates the holdback iron for a window blind, which is suitably anchored at one end in the wall of the building and is provided in its other end with a notch or recess indicated at 6, to receive a member 7 attached to the lower end of the blind indicated at B, whereby the blind is securely held in spaced relation to the building wall and against swinging movement.

The shank of the holdback iron is preferably of the form shown in Fig. 2, and to this shank, one of my improved guard devices is adapted to be attached. The guard device includes a pin or prong 8, one end of which is tapered or pointed as at 9. The other end of this guard pin is suitably fixed to the intermediate portion of the clamping plate 10. This plate is bent upon itself to provide the divergently extending arms 11, the extremities of which are inwardly bent toward each other as at 12. The opposed edges of these extremities 12 diverge from each other across the width of the clamping plate, as at 13, and at one of their ends, these edges are curved away from each other or flared, as at 14. By spacing the opposed edges of the inwardly turned ends of the plate in this manner, the same may be readily engaged with the upper curved or convex edge of the holdback iron 5, and by a downward pressure upon the plate, the arms 11 thereof are sprung outwardly over the sides of the iron. The extremities 12 of saidarms finally spring inwardly toward each other beneath the iron and the arms 11 clampingly engage the opposite sides of the shank. Thus, the upstanding pin or prong 8 is securely held in its applied position upon the holdback iron at a point between the inner face of the blind-B and the wall of the building. Birds will thus be prevented from roosting upon said iron.

As is particularly noted in Fig. 2 of the accompanying drawings, it is to be observed that the shank of the hold-back 5 has its under surface flattened and its top surface of a width less than its .bottom surface with its top surface rounded and its longitudinal sides concave in cross section, while the arms 11 inwardly of the extremities 12 are provided with the inbows 14: adapted to engage the concaved sides of the shank 5.

From the foregoing description, taken in connection with the accompanying drawing, the purpose and several advantages of my invention will be obvious. The device, as shown in Fig. 1, may be very easily and quickly applied to holdback irons for blinds now in general use, or readily removed therefrom when necessary. The invention being exceedingly simple in its construction may be produced at comparatively small manufacturing cost.

While I have shown and described the particular form and construction of the several elements employed, it is to be understood that the invention is susceptible of considerable modification therein, and I, therefore, reserve the privilege of resorting to all such legitimate changes as may be fairly embodied within the spirit and scope of the invention as claimed.

Having thus fully described my invention,

What I desire to claim and secure by Letters Patent is A bird guard comprising a guard pin, a

substantially U-shaped clamping plate fixed 5 to one end of said pin and including spaced diverging spring clamping arms having inturned extremities, the opposed edges of said extremities being divergently disposed With relation to each other and at their Wider 10 ends being flared apart to facilitate the application of the clamping plate to a support whereby the guard may be detachably applied.

In testimony whereof I hereunto aflix my signature in the presence of two Witnesses. 15
